Cell phones from nearly every manufacturer will work on our network as long as they are 4G VoLTE or 5G compatible and use a SIM card. If you already have a compatible phone, all you need to do is purchase an Ultra Mobile SIM kit.

If your 4G VoLTE or 5G compatible phone meets the following two criteria, your phone will work with Ultra Mobile:

Your phone requires a SIM card.

You have an unlocked phone.

If you begin your Ultra Mobile registration and your phone says, “Restricted” or “Contact Service Provider,” doesn’t allow you to make calls, or won’t grant access to your phone book, the phone is most likely locked. Contact your previous carrier to unlock your phone.

Check our 5G Coverage Map to find out if there is service in your area.

Our high-speed data will always attempt 5G • 4G LTE speeds, but certain locations or network conditions will render 5G • 4G LTE unavailable. Your network speed will be dependent on your location, coverage and device.

After the allotted 5G • 4G LTE data is exhausted, data speeds will be slowed. Further throttling may occur for heavy data users. For any questions about data speed, please refer to our Terms and Conditions.

5G is the fifth generation of wireless network technology that will deliver faster download speeds and enhanced connectivity, providing us the potential to experience new, innovative technologies, and transform the way we live, work, and play.

5G isn’t replacing 4G any time soon. In fact, they will coexist and work together. 5G-capable phones can use both 4G and 5G technology.

5G is already available on Ultra Mobile to anyone with an Ultra plan and a 5G-capable phone to access our 5G network. 5G coverage varies nationwide and may not be available in your area.

5G simply increases the speed that you can download files. If a file requires 2MB of data to download it on 4G, it will still be 2MB of data to download it on 5G. You may just finish downloading it faster.

To bring your 5G capable phone to Ultra Mobile, it must be unlocked and VoLTE compatible. To check compatibility, please visit: https://www.ultramobile.com/byop/#

You’ll access a nationwide 5G network you can rely on to keep you connected in more places. Our 5G coverage utilizes a 600MHz low band signal that reaches more cities and towns across America (based on analysis of leading 5G networks, July 2020).

With the iOS 18 update, you can now transfer your eSIM(s) between two iPhones. There are two ways you can transfer an eSIM between two iPhones, and the first way is during the initial setup of a new iPhone. During that process, you will eventually get to a “Transfer your Phone Number” screen, and Apple will walk you through what to do. You can also transfer an eSIM to a new iPhone manually. All you have to do is go to your new iPhone Settings, then click ‘Cellular’, and then click ‘Set Up Cellular’. Then you can set up your eSIM and transfer your phone number to your new iPhone. *Both iPhones need to be upgraded to iOS 18 or higher for the transfer to be possible.*

First, get the First Line with a 1-Month Unlimited Plan for $49/mo. Second, add up to 4 additional 1-Month Unlimited plans for only $24/mo per line. (And for a limited time, you can add a third line to your Family Plan or just $12/mo!) Third, activate your first line, then activate the remaining lines. Lastly, easily manage all lines under one account on the website or in the app More info can be found here: ultramobile.com/family-plan.

We are here to help! Check your eSIM compatibility.

With an unlocked phone, you can purchase a plan and choose eSIM as your preferred delivery option. Please check your phone compatibility at www.ultramobile.com/byop/ to ensure that your phone will work on our network.

No it won’t. You’ll get the same great 5G • 4G LTE service you would expect regardless of the SIM you’re using.

Both physical SIM cards and eSIMs securely connect you with your network and give you access to your service so you can use your plan. A physical SIM card is a small chip that is physically inserted into your phone. An eSIM is a digital chip that can be downloaded to your phone.

Please note, that if you have installed an eSIM into one device, you can’t install the same eSIM (use the same QR code) into another phone or device. You have to order a new eSIM for another device, even if you have deleted the eSIM from the first device. You have the option to transfer your eSIM between two iPhones (iOS 18 & up), but you’ll still only be able to use the eSIM in one device at a time.

Dual SIM allows users to use two phone numbers at the same time. For example, you can use one number for business and another number for personal. You can have one number linked to an eSIM and one number linked to a physical SIM. eSIM-only devices, like iPhone 14, 14 Plus, 14 Pro, and 14 Pro Max allow for two eSIMs on the same device.

An eSIM is just a physical SIM that has gone digital. Instead of physically inserting a SIM into your phone to join the Ultra network, you install an eSIM onto your phone. This means you don’t have to wait for your SIM to be delivered; you can activate it straight after purchase. If you’re new to Ultra, and have an unlocked, eligible phone you can choose eSIM at the time of purchase online or at an Ultra Mobile Retailer. Please use our store locator to find one near you.

To check whether your device is compatible, just click here. If your device is compatible and you’ve had no recent issues you should be all set. If you’re having issues with calls or texts, it might be a good idea to take a few more steps:

1. Check to see if there are any software updates for your phone that have not been installed. 2. Ensure that VoLTE is turned on. While the naming conventions may vary, the easiest way to see if VoLTE is enabled on your phone is to check within the device’s settings: Click on the Settings icon -> click ????-> type “volte” -> click VoLTE Calls Menu -> switch the VoLTE Call Toggle to “On.” If after typing “VoLTE” no menu option appears, the device either does not support VoLTE or VoLTE is defaulted to “On” which is likely if the phone is fairly new.

3. Confirm the APN settings for the device.

Our Care Team is here to help every day from 6 am to 6 pm PST. The easiest way to contact us is through our helpful chatbot, which can connect you to a live agent. You can also give us a call at 1-888-777-0446 or dial 611 from your Ultra Mobile phone.

Yes you can. You have up to 45 days from your plan purchase date to activate your SIM. We will notify you before we deactivate it. Should you need ore time, please call our Customer Care Team at 1-888-777-0446 or dial 611 from your Ultra Mobile phone.

The best way to see how much data you need is to log into your current provider portal and check your monthly data usage. You can go also go to your phone’s settings (Settings > Cellular Data for iPhone, or for Android Settings Menu > Data Usage > Select Dates for Android) and check that way.
